Method for curling hair



United States Patent 3,420,246 METHOD FOR CURLING HAIR Sterling O.Stageberg, 18210 Sunset Blvd., Redington Shores, Fla. No Drawing. FiledApr. 26, 1965, Ser. No. 451,013 US. Cl. 132-7 5 Claims Int. Cl. A45417/00 ABSTRACT OF THE DISCLOSURE Hair is curled by encasing each strandof hair in a water repellent material, then placing the hair strandsbetween complementary pressure applying members, one of which is formedof resilient material and the other of which comprises a nonyieldingblade edge curved on a radius of about .010 inch, forcing the bladeagainst hair strands by bending thereof to drive the edge of the bladeand the segments of the hairs engaged thereby to a depth in theresilient member of the order of .015 inch to bend, stretch and distortthe hair beyond its re covery point.

The present invention relates to a method of curling hair and is animprovement in the method of curling hair disclosed and claimed in myUnited States Patent No. 2,808,838.

It is well known that when a persons artificially curled hair issubjected to moisture it tends to return to a straight condition and thecurl is destroyed. This is particularly true of a water induced pin curland is true to a lesser extent with hair curled by the method of theaforementioned patent.

The principal object of the present invention is the provision of amethod of curling hair which results in curls which are unaifected bymoisture of any degree so that even complete immersion of the hair inwater will not cause a lessening of curling tendency.

In carrying out the invention, the method comprises first waterproofingthe hair by a suitable material which may be applied by dipping the hairin liquid waterproofing material, after which the hair is curled in themanner set forth in the aforementioned patent, that is, placing the hairbetween two members one of which is a bladelike element having an edgewhich is pressed to hair which is between the two members so that thehair is bent by the blade-like member under a pressure of 1,000 p.s.i.and in which bending pressure is repeatedly applied along the length ofthe hair in segments of hair in the order of .030 inch to .050 inch inlength.

In carrying out the invention, the hair is first washed and thenthoroughly dried after which it is immersed in a suitable liquidwaterproofing material to coat each hair therewith. The waterproofingmaterial may be a wax and water emulsion which when dried forms awaterproof coating over each hair, or the waterproofing material may beof a penetrating type which penetrates the hair and deposits waterrepellent material therein. The latter waterproofing agent may be of theso-called silicone ty e. Suitable waterproofing materials are readilyavailable on the market and are well known, and ordinarily are used intreating cloth and the like to render the same water repellent.

After the hair has been treated with waterproofing material asdescribed, it is dried by heated air passed through the hair, the airtemperature being as high as can be accepted by the person. Followingthe drying step the hair is then subjected to bending and stressing toIce provide curling thereof as set forth in the aforementioned patent soas to produce curls therein. By forming the curls after the hair hasbeen waterproofed, the hair is impervious to moisture and therefore itwill retain its form regardless of the amount of moisture which may comeinto contact with the hair.

Furthermore, I have found that treating hair as described herein has atherapeutic value and the hair of the curls is glossy rather than dull,and the treatment imparts a lively, healthy appearance to the hair. Thewater repellent on the individual hairs sheds any water to which thehair is subjected whether from swimming, bathing, etc. and the curlsremain unaffected.

Although I have described but one form of the invention, it is to beunderstood that other forms, modifications, and adaptations could bemade all falling within the scope of the claims which follow.

I claim:

1. A method of curling hair which comprises coating individual hairswith a water repellent material in liquid form, substantially dryingsaid material on the hairs and then curling the hair by subjecting eachhair to a bending pressure in the order of 1,000 p.s.i., the bendingpressure being repeated along the length of each hair and theapplication of pressure being confined to a portion of a length of thehair in the order of .030 inch to .050 inch at each application of thepressure.

2. A method of curling hair which comprises drying the hair, coating thehair with a waterproofing agent comprising a wax emulsion in water,substantially drying said material on said hair, and then curling thehair by subjecting each hair to a bending pressure in the order of 1,000p.s.i., the bending pressure being repeated along a length of each hairand the application of pressure being confined to a portion of thelength of the hair in the order of .030 inch to .050 inch at eachapplication of the pressure.

3. A method of curling hair which comprises coating the hair with awaterproofing agent in liquid form comprising a silicone, substantiallydrying said agent on the hair, and then curling the hair by subjectingeach hair to a bending pressure in the order of 1,000 psi, the bendingpressure being repeated along a length of each hair and the applicationof pressure being confined to a portion of the length of the hair in theorder of .030 inch to .050 inch at each application of the pressure.

4. A method of curling hair which comprises washing the hair, drying thehair, coating each hair with a waterproofing agent in liquid form,substantially drying the coated hair, and then curling the hair bysubjecting each hair to a bending pressure in the order of 1,000 p.s.i.,the bending pressure being repeated along a length of each hair and theapplication of pressure being confined to a portion of the length of thehair in the order of .030 inch to .050 inch at each application of thepressure.

5. A method of curling hair which comprises coating the hair with awaterproofing agent in liquid form, substantially drying the coatedhair, and then positioning the strands of hair between complementarypressure applying members, one of which is formed of resilient material,and the other of which is in the form of a nonyielding blade, an edge ofwhich is convexly curved on a radius of approximately .010 inch, withthe hair extending crosswise of said edge of said blade; bringing saidpressure applying members together with a force sufiicient to drive theedge of the blade into the resilient member to a depth on the order of.015 inch to thereby apply mechanical pressure laterally on a minutepor- 3 4 tion of the hair, on the order of .030 inch to .050 inchReferences Cited long, which pressure is sufiicient to bend, stretch anddis- UNITED STATES PATENTS tort the hair beyond its recovery point; andrepeating said pressure application while effecting relative movementbetween the hair and the complementary pressure 5 applying memberslengthwise of the hair so that the deformations of the hair thusproduced occur at close LOUIS MANCENE Examme" intervals along the lengthof the hair.
